UNITED STATES NAPOLEON B. LILES, OF BLACK MOUNTAIN, NORTH CAROLINA.

DJUSTABLE QNE-RAS ENGER SEESAW.

Application filed September 21-, 1925.

To all whom it may concern:

Be it known that I, NAPOLEON B. LILES, a citizen of the United States,residing at Black Mountain, in the county of Buncombe, State of Northnew and useful Adjustable One-Passenger Seesaw, of which'the followingis a specification. f Y

My invention relates to one-passenger seesaws which can be adj usted tosuit the weight of the child using the same, the objects being toprovide a see-saw or swing which can be attached to the wall of abuilding, a post, or to any desired form of support. further object of 1y invention is to provide a see-saw or swing on which one child mayswing, and is especially adapted to be placed in homes where thereis'only one child, thus giving the child the advantages of a see-sawswing at any time he desires to use the same.

Other objects of invention will appear as the description proceeds,reference being had to the accompanying drawings in which Figure 1 is aperspective view of my device;

Figure 2 is also showing lines;

Figure 3 is a detail view showing the means for holding the adjustingbar in place;

Figure is a detail iew of a section of the adjusting bar. r

Having thus briefly described the different figures in the drawings, adetailed descrip tion of the drawings will now be given in which likereference characters indicate corresponding parts throughout thedrawings.

The numeral 1. indicates the portion of my device which is adapted to besecured to the wall of a building, to a post, or to any other desiredform of support. This portion 1 has holes 2 therein for the reception ofthe bolts or wood screws 3 which are adapted to penetrate the support aand hold the device firmly to the desired form of support.

side elevation of my device,

a it in raised position in dotted her. 1 is the board 5, which issecured to the 6. The end portion of the board 5 which farthest removedfrom the hinges has cut away portions 7 in which the legs of a childwill fit when the child is seated thereon for swinging. Immediatelyforward of these cut away portions there is an upright post 8 securedtothe board 5, and said upright post Carolina, have invented a justingSecured to the lower portion of the mem- .Serial no. 57,711.

has a cross-bar 9 secured to the top of the uprightpost, which serves asa handle for the child while seated on the board 5.

Approximately along the longitudinal center of the board 5 and on theupper side thereof is secured the adjusting bar 10, which is secured tothe board 5 by means of hooked bolts 11, said bolts penetrating theboard I) and having nuts on their lower ends, as is clearly shown inFigure Any desired means, such as an eye bolt 12 may be secured to theupper center portion of the member 1, and to this eye-boltis secured thecoiled spring 13, which has a snap hook on its lower end, said snap hook14 being adapted to engage any one of the holes 15 in the adjusting bar10, the purpose of this adjustment being to allow the device to beadjusted to suit the weight of the child which is to swing thereon.

The adjusting bar may have a notch 16 in its upper edge for thereception of the hooked bolts 11-, and thus prevent the adbar fromslipping.

The method of operation is as follows:

The device is secured to any desired form of support, such as a wall, apost, a series of. parallel timbers mounted on posts and parallel withthe ground, or any desired form which may be best suited to thecircumstances. The child is placed on the seatof the device, and thespring tension is adjusted by means of placing the snap hook in thedesired hole in the adjusting bar 10, and the child's feet touch theground, but the tension of the spring 13 almost lifts the child from theground or floor as the care may be. When the child places its feet tothe eund and gives a slight jump, the board 0 will raise the child fromthe ground to a predetermined point as shown by the dotted lines inFigure 2, or to even a greater height, depending on the tautness of thecoiled spring and the force exerted by the child in its jump. lVhen thechild has reached its highest point from the ground or floor, the board5 will descend, carrying with it the child seated thereon, and thechilds feet will touch the ground, and another jump will be made by thechild, and

this operation will continue as long as desired. it is thus seen thatthe child will get the same motion as in a see-saw operated by twochildren, one on each end of the conventional see-saw, and at the sametime, 'undesirable playmates will not have to be endured for the sake ofoperating a see-saw. It is desired to be understood that I am notlimitedto the partlcular form oit Wall support as illustrated, but it may bestated a bar that instead of the member 1, the hinges may be attached toa timber parallel with the ground or floor, and the eye-bolt 12 may besecured to another timber parallel with the timber to which the hingeson the board 5 are attached. This would be especially desirable should aplurality of these devices be installed in a play-ground.

Having thus fully described a preferred embodiment of my invention, WhatI desire to protect and secure by Letters Patent of the United States isas follows:

I claim:

In an amusement device, a Vertical support, a seat portion hingedlysecured to'the vertical support and adapted to swing in a verticalplane, a handle-bar rising vertically from the upper portion of the seatportion, secured to the upper side of the seat portion and extendinglongitudinally of the seat portion from a point near the handle bar to apoint in close proximity to the point Where the seat portion is hingedlysecured to the vertical support, holes in the bar, a coiled springhaving one of its ends secured to the vertical support at a point aboveWhere the seat portion is secured to the vertical support and having" ahook on its other end adapted to be inserted in any one of the holes inthe bar.

In testimony that I claim the foregoing as my own I have hereuntoatlixed my signature this'the 17th day of September, 1925.

NAPOLEON B. JILES.
